So Miley Cyrus twerked last weekend. Some people had a problem with this. (Probably foremost is Sir Mix-A-Lot, but I'm just guessing here.)
One of the complaints is that Miley is racist for stealing an element of black culture. Seriously.
If you have a culture that is identified with twerking, your culture is terrible. That's not a culture, that's a rap video. Culture is the shared set of values and practices that create community identity. A rap video is a caricature of sexuality and materialism. When your shared set of values and practices is a caricature of sexuality and materialism, your community is worthless.
Other angry people have been angry about the notion of "black culture." Instead of being seen as a homogenous group with identical tastes and behaviors, they want to be seen as individuals. But then why do things like "the black vote" and "acting white" continue to exist? A massive percentage of American blacks behave as a homogenous group with identical tastes and behaviors; 98% of young black women voted for Barack Obama in 2012. If you don't want to be seen as clones, don't behave like clones. If you don't want to be identified with a deficient culture, don't allow your culture to become deficient.
